Hello all!

Would anyone know what are the equations to calculate standard deviation of a study for different study designs (2x2, 2x3x3, 2x2x3, 2x2x4)?
For example, standard error of a study for a given parameter is given in Phoenix Winnonlin with "Diff_SE" in the "Average Bioequivalence" tab but I cannot either find or calculate its standard deviation.

I assume it has something to do with coefficients and number of subjects in sequences like in known.designs() but I cant get my head around it :confused:
